Waltham Attacker 3 Months Later: Postal Service Offers $5K Reward

WALTHAM, MA — The U.S. Postal Inspection Service renewed its call to find information leading to the arrest and conviction of the person or persons involved with the random violent attacks in Waltham, which comes with a reward of up to $5,000.

"The U.S. Postal Inspection Service is offering a reward of up to $5,000 for information leading to the arrest and conviction of the suspect(s) involved with random attacks/assaults on men in the town of Waltham, Massachusetts since November 10," the service said in a statement.

The Waltham Police Department said the investigation was the priority in its last public update on Jan. 5. Since then, little new has been made public.

"The investigation is ongoing and while I do not have anything new for you today," Det. Sgt. Tim King said in an email March 1. "I can tell you that we expect to be releasing some new information in the near future."

Between Nov. 12 and Nov. 27 someone hid using the cover of darkness —between 5:30 and 11:30 p.m. — before attacking unsuspecting men around the city, sending many of them to the hospital with serious injuries to the head and face, including a postal carrier. The assailant ran off in each case without stealing anything, police said.

Police said there have been 11 attacks reported, but after they offered a reward for information leading to the arrest and conviction of the assailant on Dec. 1, the attacks stopped.

Then-Chief Keith MacPherson said his department has all available resources, including a drone, focused on catching the person or persons responsible.

"The motive is somewhat in question, but it appears to be a thrill of the assault or someone who is very violent and enjoys seeing someone hurt," MacPherson said Dec. 1.

The first attacks happened at the Gardencrest apartment complex, while more recent attacks happened downtown in the area of Chestnut and Charles streets.

In late November, police released a 4-second video clip showing a man running down the street in jeans and a black sweatshirt and asked for the public's help identifying him in connection with the attacks. Police said they are looking into other persons of interest, thanks to tips from the community.

One of the most difficult aspects of the case has been getting an accurate description of the person responsible. Descriptions of the attacker or attackers have varied between white and Black men of various heights, because most people have been surprise attacked from behind.

Waltham resident David Camaros told Patch previously he was on the phone throwing out trash behind his apartment building on Middlesex Road when someone attacked him from behind using a heavy object.

The department has asked that anyone who has witnessed an assault to call police at 781-314-3600 (option 4) or the anonymous tip line at 781-314-3636.

The postal service is asking people call 877-876-2455.
